3 Claims.

Other objects of the invention are to ovide an improved mechanical pencil point of t e charac- 10 ter described whichlwill be comparatively simple in construction, compact, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become ap- 16 parent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of ref rence designate corresponding parts throughou the several views, and wherein:

m Figure 1 is an elevational view of a mechanical pencil embodying-the present invention.

Figure 2 is an enlarged'view of the point with the lead therein, the enlargement constituting .the present invention being shown in vertical sec- II tion.

g Figure 3 is a view substantially similar to Fig.

2 but showing a other form of the invention.

Referring now to the drawing in detail, it will be seen that thereference numeral 1 designates- 80 the usual barrel of a mechanical pencil which is provided with a pocket clip 2 and aneraser I. Rotatably mounted on the lower end of the barrel 1 is a tapered point 4 having a central aperture therein for the reception of the lead, as

I! at i. The tapered point 4 contains the usual figcdhmism for projecting and retracting the The point I includes a tapered tip end, said tip being of suitable material, prefera ably metal. The tip 8 is also centrally apertured to receive the lead-1.. At-its lower end, the tip I terminates-in an enlargement I of substantially the shape shown to advantage in Fig. 2 of the g In use, the enlargement I provides a convenient grip or knob to facilitate rotating the point 4 for proiectingorretractingthelead I. Ifdesired,the enlargemmt I may be knurled or roughened in I on its lower order that a better grip may be had thereon. It will be observed that the shape of the enlarge! ment I is such that it interferes in no waywith writing when the pencil is held at different angles relative to the writing surface, as suggested in 6 Fig. 1 of the drawing. Theenlargement 1 also greatly' facilitates inserting the pencil in the pocket as said enlargement readily opens said pocket in advance of the pencil without tearing, puncturing or otherwise damaging the fabric. 10 The enlargement 1 also functions as a shield to prevent injury if the pencil is fallen on. Stillfurther, the enlargement I strengthens or reinforces the point of the pencil.

In the modification illustrated in Fig. 3 of the 16 drawing, the reference numeral 8 designates an enlargement which is adapted to be screwed or otherwise firmly secured in position on'mechani cal pencils which are manufactured as at present.

Of course, the head 8 functions in a manner simgo ilar to-the enlargement 1.

It is believed that the many advantages of an improved mechanical pencil point constructed in accordance with the present "invention will be readily understood and although preferred-em- 25 bodiments of the device are as illustrated and described, it is to be understood that further modiflcations and changes in the details of constructlon may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

in said pocket.
